The workshop structure was engineered and supplied by Eurban Ltd and comprises five glulam portal frames spanning 10 metres, 'wrapped' up with 60mm crosslam (CLT) panels to roof and walls. The CLT roof panels were pre-fixed to 360mm glulam purlins which were dimensioned and spaced to accommodate 500 straw bales as roof insulation. The wall CLT has a home-grown softwood sub-frame fixed on the outside to hold 200mm of conventional insulation.
